阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项。
A
Imagine landing in a foreign country where you cannot speak the language, understand the culture and don’t know anybody. Wouldn’t it be nice to have a friend who could help you out?
John Smith, an English explorer who landed in America in 1607, found the best friend ever. She was a Native American named Pocahontas (1595-1617). And she did more than teach Smith the language: she saved his life, twice.
Smith was captured by members of Pocahontas’s tribe (部落) and was going to be killed. But for some reason, the Chief’s daughter, Pocahontas, felt sorry for Smith (who was probably the first white man she had ever seen) and threw her body over his to protect him. Smith returned safely to the small village he was living in.
During the winter the English settlers did not know how to get food from nature. Pocahontas often brought food for Smith and his friends.
A year later Pocahontas’s father tried to kill Smith again because the Native Americans were very scared the English would try to take over their land. Pocahontas warned him and he was able to escape.
Later she became a Christian and eventually married an Englishman named John Rolfe.
She spent the last year of her life in London.
Pocahontas has become an American legend (传奇). Her life story has been re-created in many books and films, including Disney’s 1995 film, Pocahontas.
One of the reasons she is so popular is that many Europeans look at Pocahontas as an excellent example of how a minority can adjust into the majority. Pocahontas is also respected because of her selfless love. She proved that people can be kind and loving even to people of a different race or culture. John Smith was very different from Pocahontas but she could see he was a good man and that was all that mattered. No race or country owns goodness, love and loyalty.

D. People from different cultures can never really get along well with each other.
B
Chinese students aren’t the only ones who have a sleep loss problem. In Australia, teenagers are also missing out on, on average, one hour’s sleep every night during the school week.
Organized activities and homework push bedtimes later, the first large-scale Australian study of children’s sleeping habits has revealed (显示). Their sleep deprivation (剥夺) is enough to cause “serious drop-offs in school performance, attention and memory”, and governments should consider later or flexible school start times, said the study’s leader, Tim Olds.
His survey, of more than 4,000 children aged 9 to 18, found those who slept least did not watch more television but spent their time socializing (相处) with family or friends or listening to music.
“Almost all children get up at 7 or 7:15 — they have to get to school on time,” said Olds. He favors a later start over an earlier finish because he believes organized sports and activities would still consume the latter end of the day.
Olds’research also establishes lack of sleep as a cause of weight gain in children, and a possible source of future problems with depression, anxiety and increased susceptibility (易感性) to illness.
It was already known that overweight children sleep less, but Professor Olds found sleep duration (时长) was strongly linked to weight across the full range of body sizes. The thinnest children sleep 20 minutes more than the obese. This showed being overweight had no specific effect on sleep patterns, and it was more likely that shorter sleep times stimulate (刺激) appetite and make kids hungry.
The US National Sleep Foundation says teenagers aged 13 to 18 need eight to nine hours’ sleep a night. Younger school-aged kids need 9 to 11 hours.
On that basis, Professor Olds said, half of Australian children are under-sleeping on weekdays and a quarter on weekends.
6. The Australian students surveyed don’t sleep enough because they spend more time on the following EXCEPT _____.
A. organized activities and homework
B. communication with friends and family
C. watching television programs
D. enjoying music
7. What effects does lack of sleep directly have on the students according to the survey?
A. They become overweight but begin to eat less than before.
B. They feel more depressed and anxious about their school work.
C. They are more likely to be affected with illness in the future.
D. They pay less attention in class and their memory declines.
8. Which of the following suggestions did Mr. Olds raise?
A. The students should go to bed earlier to have longer sleeping time.
B. The students should participate less in organized activities.
C. The school should put off the start time in the morning.
D. The school should finish earlier in the afternoon.
9. What does "obese" in the sixth paragraph mean?
A. average B. fat C. sleepless D. overeating
10. Which of the following statements is TRUE?
A. Australian students usually take part in activities in the afternoon.
B. More students are short of sleep on weekends than on weekdays.
C. Being overweight has an effect on the length of the sleeping time.
D. The survey suggests that teenagers need 8-9 hours’ sleep a night.
C
By day he is just a normal cat but when the lights go out, he glows (发光) in the dark.
Scientists have genetically modified (更改) a cat as part of an experiment that could lead to treatments for diseases.
Named Mr. Green Genes, he looks like a six-month-old cat but, under ultraviolet (紫外线的) light, his eyes, gums (牙龈) and tongue glow green. That is the result of a genetic experiment at the Audubon Center for Research of Endangered Species in New Orleans, US.
Mr. Green Genes is the first fluorescent (荧光的) cat in the US and probably the world, said Betsy Dresser, the center's director.
The researchers made him so they could learn whether a gene could be introduced harmlessly into a cat's genetic sequence (次序).
If so, it would be the first step in a process that could lead to the development of ways to treat diseases via gene therapy (治疗).
The gene, which was added to Mr. Green Genes' DNA, has no effect on his health, Ms Dresser said.
Cats are ideal for this project because their genetic makeup is similar to that of humans, said Dr Martha Gomez, a scientist at the center.
To show that the gene went where it was supposed to go, the researchers settled on one that would glow.
The gene "is just a marker"，said Leslie Lyons, an assistant professor at the University of California, Davis. Lyons is familiar with the center's work.
"The glowing part is the fun part," she said.
Glowing creatures made international news earlier this month when the Nobel Prize in Chemistry was awarded to three scientists who had discovered the gene through their work with jellyfish (水母).
11.Which of the following might be the best title for the passage?
A. A Glowing Cat B. Mr. Green Genes
C. One Cat’s Life D. An experiment on cats
12. What can we conclude from the passage?
A. Fortunately, scientists have found ways to treat diseases via gene therapy.
B. Scientists think cats’ genetic makeup is the same as that of human beings.
C. Three scientists who had discovered the gene were given Nobel Prize in Physics.
D. Scientists have managed to introduce a gene into a cat’s genetic sequence.
13. What does “settled on” most probably mean in Paragraph 9?
A. chose B. killed C. took D. raised
14. From the passage we can see that ____.
A. Mr. Green Genes was made by researchers to treat diseases
B. the cat named Mr. Green Genes can glow when it is dark
C. Mr. Green Genes is the first fluorescent cat in the world
D. Mr. Green Genes is a cat of seven months old up to now
15. Which of the following is WRONG according to the text?
A. The gene added to Mr. Green Genes’ DNA doesn’t affect its health at all.
B. The scientists came up with the idea of the glowing genes totally for fun.
C. Earlier this month glowing creatures became news all through the world.
D. Scientists had discovered the gene from the jellyfish they worked with.
Climate has been a major driver of armed conflict in Africa, research shows—and future warming is likely to increase the number of deaths from war. US researchers found that across the continent, conflict was about 50% more likely in unusually warm years.
Writing in Proceedings of the National Academy of Sciences (PNAS), they suggest conflict arises when the food supply is not enough in warm conditions. Climatic factors have been mentioned as a reason for several recent conflicts. One is the fighting in Darfur in Sudan that has killed 200,000 people and forced two million more from their homes. Previous research has shown an association between lack of rain and conflict, but this is thought to be the first clear evidence of a temperature link.
The researchers used databases of temperatures across sub-Saharan Africa for the period between 1981 and 2002, and looked for connections between above average warmth and civil conflict in the same country that left at least 1,000 people dead. "Studies show that crop output in the region is really sensitive to small shifts in temperature, even of half a degree or so," research leader Marshall Burke, from the University of California at Berkeley, told BBC News.
"Our findings provide strong motivation to increase investments in African adaptation to climate change by such steps as developing crop varieties less sensitive to extreme heat and promoting insurance plans to help protect farmers from negative effects of the hotter climate," said Dr Burke. "If the argument is that the trend towards rising temperatures will increase conflict, then we need to do something around climate change, but more fundamentally we need to resolve the conflicts in the first place."
If the sub-Saharan climate continues to warm and little is done to help its countries better adapt to high temperatures, the human costs are likely to be unimaginable. If temperatures rise across the continent as computer models project, future conflicts are likely to become more common, researchers suggest. Their study shows an increase of about 50% over the next 20 years.
When projections of social trends such as population increase and economic development were included in their model of a future Africa, temperature rise still emerged as a likely major cause of increasing armed conflict. At next month's UN climate summit (峰会) in Copenhagen, governments are due to debate how much money to put into helping African countries prepare for and adapt to negative effects of climate change.
68. According to the passage, which of the following is one of the reasons for the fighting in Darfur in Sudan?
A. Shortage of drinking water. B. Racial discrimination.
C. Rising temperature. D. Demand for planting land.
69. What can we know from the research done by the US researchers?
A. There is no close relation between rainfall and conflict.
B. Temperature greatly affects crop production in sub-Saharan Africa.
C. Temperature will rise by about 50% in Africa over the next two decades.
D. With world cooperation, conflicts in Africa will be reduced by half 20 years later.
70. What can be inferred from the passage?
A. Something must be done to help sub-Saharan countries with better adaptation to climate change to avoid disaster.
B. Conflicts in sub-Saharan countries are sure to be on the rise in future.
C. Temperature in sub-Saharan countries will rise at a faster speed.
D. High temperatures will make sub-Saharan countries unfit to live in.
Still want a laptop? That was so yesterday. Get ready for the next stage in the personal computer revolution: It's the ultrathin (超薄的), cheap netbook.
According to a New York Times report last week, personal computers are about to go through their biggest change since the rise of the laptop. By the end of the year, consumers are likely to see laptops the size of thin paperback books that can run all day on a single charge and are equipped with touch screens or slide-out keyboards. The netbook is a kind of portable computer with learner functions for online surfing and basic computing activities, for example, word processing. To cut the cost and weight, they usually have a low-powered processor, small screen, narrow keyboard, and no ODD.
Currently, some of the devices look more like a toy than a full-feature computer. That's because most of the netbooks sold today run on an Intel chip called Atom. This is a lower-power version of the company's standard laptop chip, so they have trouble running demanding software like games and photo-editing programs.
This year, a group of companies who make cheap, power-saving chips used in cell phones are applying that expert skill to PCs. That means they will break Atom's netbook dominance (统治地位) and reduce the size while letting it run complicated programs.
The big winner in the rise of netbooks will be the consumer. AT&T announced last week that customers in Atlanta, Georgia, US, could get a netbook for just $50 (342 yuan) if they signed up for an Internet service plan. This trend will soon spread to Asia, according to industry experts.
University campuses are a major target of Shanzhai netbooks—uncopyrighted (无版权的) domestic copies of foreign brands. These products are usually sold at less than 2,000 yuan. But industry insiders suggest students not use these nameless products because many of them don't provide good after-safes services.
64. The following are all advantages of netbooks EXCEPT that.
A. people can easily edit photographs with them B. they cost less than other personal computers
C. they are very thin and easy to carry D. they save power
65. Why are students advised not to use Shanzhai netbooks?
A. Because they are of poor quality.B. Because they are not easy to operate.
C. Because they will soon be out of date. D. Because they lack good after-sales services.
66. What can be inferred from the passage?
A. Laptops are becoming more and more popular.
B. University students seldom buy Shanzhai netbooks.
C. Shanzhai netbooks are sold better than those of famous foreign brands.
D. Atom's netbooks make up the largest part of the sales of portable computers at present.
67. What is the general idea of this passage?
A. Shanzhai netbooks are taking control of laptop market.
B. Netbooks have advantages over laptops in everything.
C. Netbooks are becoming the trend of personal computers.
D. Most of the netbooks sold today run on an Intel chip called Atom.
Across the United States, there are several places where two independent towns grew together to become one city — but kept both their names.
WinstonSalem is one of them. It’s a midsized city in what’s called the plateau（high land）, between the Atlantic Coast and the inland mountains in the state of North Carolina. The Winston part is a relatively new place, founded early this century. It’s home to the nation’s biggest openair tobacco market.
The giant R.J. Reynolds Tobacco Company’s headquarters is in WinstonSalem, and Winston is the name of one of Reynolds’ bestknown cigarette brands. Fast-growing Winston soon surrounded the much older town of Salem, so in 1913, people in the area voted to combine them into a single place.
From a historical and tourist point of view, Salem, or Old Salem, as it’s called today, is the interesting and unusual part of town.
Salem was founded in the 1700s by the Moravians. They spoke German, and their community was religiously based, with single men and single women living apart in separate dormitories. The Moravians greatly valued women’s work and brainpower. In fact, one of the nation’s oldest boarding schools for young women— the Moravians’ Salem Academy founded in 1772 — is still in operation.
Over the years, Salem lost its Moravian character. That all changed, though, when a nonprofit group began to rehabilitate the historic area. These days Old Salem is what’s called a living history museum, with exhibits, music, and tours of 18th-century houses, taverns and Moravian dormitory buildings just seven blocks from the tallest skyscraper in Winston-Salem.
The historic community is booming again. Just as R. J. Reynolds is taking in millions of dollars making cigarettes across town, Old Salem is generating about $15 million a year in tourism revenue and donations.
60. From the passage we can know that____________.
A. Winston-Salem is the name of a cityB. Salem is home to the tobacco market
C. the city Winston-alem has two namesD. Old Salem is the name of a tobacco brand
61. The city Salem is special for its__________.
A. boarding schoolB. lifestyle and traditionC. respect for brainpower D. religious belief
62. The underlined word “rehabilitate” in Paragraph 6 is closest in meaning to “_________”.
A. reconstruct B. evaluate C. enlarge D. decorate
63. What will probably be talked about in the following part?
A. Some other attractions in Winston-Salem. B. How Winston makes profits from tourism.
C. Other examples of cities combined by two parts.D. Something about the boarding school for women.

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
In their book Time to Eat the Dog: The Real Guide to Sustainable Living, Robert and Brenda Vale say keeping a mediumsized dog has the same ecological impact as driving 10,000 km a year in a 4.6 liter Land Cruiser.
“We’re not actually saying it is time to eat the dog. We’ re just saying that we need to think about and know the ecological impact of some of the things we do and that we take for granted.”
Constructing and driving the jeep for a year requires 0.41 hectares of land, while growing and manufacturing a dog’s food takes about 0.84 hectares — or 1.1 hectares in the case of a large dog such as a German shepherd.
Convincing flesheating cats and dogs to go vegetarian for the sake of the planet is a nonstarter, the Vales say. Instead they recommend keeping “greener”, smaller, and more sustainable pets, such as goldfish, chickens or rabbits.
The book’s playful title, and serious suggestion that pet animals may be usefully “recycled”, by being eaten by their owners or turned into pet food when they die, may not appeal to animal fans.
Annoying as the idea may be, the question is valid given the planet’s growing population and limited resources, Robert Vale said.
“Issues about sustainability are increasingly becoming things that are going to require us to make choices which are as difficult as eating your dog. It’s not just about changing your light bulbs or taking a cloth bag to the supermarket,” he said.
“It’s about much more challenging and difficult issues,” he added. “Once you see where cats and dogs fit in your overall balance of things, you might decide to have the cat but not also to have the two cars and the three bathrooms and be a meat eater yourself.”
56. The authors gave their book the playful title to________.
A. make it amusing B. create a vivid imageC. show writing skills D. arouse people’ s concern
57. In Paragraph 3 the writer mainly wants to tell us________.
A. the amount of consumed land B. the neglected ecological impact
C. some familiar examples D. some actual figures
58. What does “sustainability” mean according to the passage?
A. Going vegetarian. B. Raising cats and dogs.C. Using a cloth bag. D. Keeping a greener life.
59. What do the authors think of living a sustainable life?
A. Challenging. B. Inspiring. C. Inviting. D. Touching.
Since the gene, called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging, immunity(免疫)and resistance in humans, the scientists said.
“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity,” said Robin May of the University of Birmingham, who led the study.
Populations across the world are aging at a surprising pace, bringing potentially big challenges for health and social care systems. A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays. Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend.
“What we have found is that things like resistance and aging tend to go hand in hand,” May said in an interview.
May’s team compared longevity, stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAF-16 in each of the four species, and found that they were all quite distinct.
May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes, which scientists believe play a role in the aging process.
“The fact that subtle（微妙的）differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution,” May said.
67. In which section may the text appear in a newspaper?
A. Education. B. Science. C. Entertainment. D. Culture.
68. What can we know from the third paragraph?
A. New ways have been found to affect aging. B. Babies in the rich world will all live longer.
C. Present social care systems are poorly managed. D. Aging populations are causing more challenges.
69. From the text we know that DAF-16_____.
A. is a gene that is only found in worms B. can make people live longer
C. has an effect on aging and immunity D. has been quite familiar to scientists
70. What can be the best title of the passage?
A. Scientists Find Gene Linked to Aging B. Population Aging Faster than Expected
C. How to Make People Live Longer D. Gene Determines How Long We Live
